Application filed July 7, 1911.

T all whom it may concern:

Be it known that I, ARTHUR F. ENGEL, a citizen of the United States, residing at 3(, 5309 Broadway, New York, N. Y., have imented new and useful Improvements in Eyeleting-Machines, of which the following is a specification.

This invention relates to eyeleting machines, and more especially to machines of this type adapted to be used in fastening papers together.

One of the objects of the invention is to provide a machine by means of which the eyelets may be readily and quickly inserted in position and upset or riveted at one and the same operation.

A further object is to provide a device which will be positive in action and which will not be liable to get out of order.

Other objects will be in part obvious and in part pointed out hereinafter.

In the accompanying drawing showing an illustrative embodiment of this invention and in which the same reference numeral refers to similar parts in the several figures, Figure l is a side view of the device, parts being broken away for the sake of clearness. Fig. 2 is. a front view of the device, part being shown in section. Fig. 3 is a bottom view of the device. Fig. 4 is a sectional view taken on the line 44 of Fig. 1. Fig. 5 is a detailed view of the plunger and eyelet cutting mechanism. Fig. 6 is a top plan view of Fig. 5. Fig. 7 is a sectional view taken on the line 7-7of Fig. 5 and showingthe eyelet feeding mechanism. Fig. 8 is a to plan view of a detail.

Referring to the gures, 1 represents the body portion of the apparatus, and 2 represents the handle portion pivotally supported thereon, as by a pivot 3. The lower end of the handle portion is provided with a recess 4 and a slot 5 for a purpose hereinafter described. The handle is maintained in its upright or normal position, as indicated in solid lines in Fig. 1, in any suitable manner, as, for example, by a spring 6, one end of which engages the body portion 1, and the other end of which engages the handle portion 2.

The machine is especially adapted to be used in connection with strips of connected eyelets, such as are shown and claimed in my copending application No. 634,022, filed June 19th, 1911.

As clearly shown in Figs. 1, 4 and 7, a

Specification of Letters Patent.

Patented Mar. 23, 1915.

Serial No. 637,272.

guideway 7 is provided in which the strip of eyelets 8 is adapted to be held and through which it is adapted to travel. This guideway is preferably made removable and may be held inposition in any suitable manner, as, for example, by a screw 9. The eyelets are introduced into the guideway through a suitable opening at the rear of the device, as shown clearly in Fig. 1.

The manner of feeding the eyelets forward into operative position with the punch and riveter or upsetter will now be described.

Pivotally mounted upon the body 1 of the device is an arm 10, one end of which is provided with a pin 11 adapted to engage within the recess 4, and the other end of the arm 10 is provided with an eyelet-engaging member 12, which is preferably resilient and formed as shown in Fig. 1. On account of the resiliency of the member 12, its free end is constantly urged into engagement with the eyelets. The recess 4 is of such length that when the handle portion 2 is in its normal position, the wall at one end of the recess will engage the pin 11 of the arm 10 and hold the arm in the position shown in solid lines in Fig. 1, which is the advanced position of the arm. When the handle portion is moved into its alternate position, as indicated in dotted lines in Fig. 1, the wall at the opposite end of the recess 4 will engage the pin 11 to move the arm 10 into the position indicated in dotted lines in Fig. 1, in which position the free end of the eyelet engaging member 12 will be moved backward to engage one of the eyelots in the rear, and it will be understood that as the handle portion 2 regains its normal position, the arm 10 will be moved forward to occupy its normal position, during which movement the eyelets will be fed forward to bring another eyelet into operative relation with the punch and riveter. Backward movement of the eyelets is prevented as by means of a spring 31 the free end of which extends into the path of the eyelets.

From the above description it will be understood, therefore, that at each operation of the handle portion 2, the eyelets will be fed forward, and such feeding movement takes place practically at the end of the anism which comprise the eyelet fastening means will now be explained :13 indicates a guiding block in which the hollow plunger l'i is adapted to reciprocate, and the reciprocating movement of the plunger is ellected by means of a stud 15 which is secured thereto and which has an inwardly bent portion 16 engaging with the slot 5 in the lower portion of the .iandle 2. The slot 5 is formed with four distinct portions which are so arranged relatii'ely to the pivot about which that the plunger will-be the han he moves actuated in the following manner: During the initial nunement of the handle, the plunger ll and the punch 17, which is mounted therein, will be urged downward a distance sullicient to force the punch through the papers and to force the eyelet through the hole punched through the papers by the punch. As the downward movement oi the handle continues, the plunger and punch are raised and are then held stationary, for a purpose hereinafter described, and during the final downward movement of the. handle, the plunger is depressed a farther distance for the purpose of upsetting or riveting the eyelet. The punch 17 is free to move with respect to the plunger, but is held in its normal position and is prevented from tallin g out in any suitable manner, as, for example, by means of the stud 15 engaging a shoulder formed on the punch, as shown in Fig. 2. As shown in Fig. 1, the lower end of the punch normally projects beyond the or end of the plunger and it will be understood from the above description that as the handle is forced downward, the plunger and punch will descend together, the punch passing first through the eyelet and then being forced through the papers to he fastened, and the plunger engaging the flange of the eyelet through which the punch has passed, will force the eyelet into the papers. The eyelet is preferably normally held in position by a resilient member 18, which, as shown, consists of a piece of spring metal having its upper end fastened to the guide block 13 and having its lower or free end turned in slightly to engage with the lower surface of the flange of the eyelet, as clearly shown in Fig. 1. As the plunger 14 descends into engagement with the flange of the eyelet, it will force the eyelet downward. the member 18 moving aside on account of its resiliency to release the eyelet, and, as soon as the plunger returns to its normal position and the eyelet is released, it springs hack and assumes its operative position in readiness to engage the flange of the next eyelet, Which is fed into its operative position by the mechanism above described.

19 indicates a slidahle member provided with a die or opening 20 and with an upsetting or riveting recess 21. The member 19 is also provided with an upwardly extending arm 22, which may be integral therewith, and which is provided with a recess in its upper portion adaptel to be engaged by a pin 21 carried by the handle 3. The member 19 may be slida l held in position in any manner, as. for example, by pins 25' and 26 engaging slots :37 and 28' respectively. In its normal position, as shown in Fig. 1, the member 19 is so held that the hole or die 20 is beneath and in registry with the punch 17, and the member is maintained in this position during the time that the punch descends through the eyelet and through the papers for the puri vose ot punching a hole therein. filter the punch has been raised out ot the die the member 1!) is then moved torn aid to bring the riveting recess 21 into registry with the hzwer edge of th eyelet 8. This movement of the member 19' is brought about the pin .21 striking against the shoulder of the slot 2 5 during the downward lll(l-.Plll0lit ot' the handle 2 and upon the further downward movement of. the handle 1. as al-ove,described. the plunger engages the upper flange of th eyelet and forces the eyelet downward, whereby the lower edge thereof forced into the recess 21 will be upset or riveted. During the movement of the handle, the punch 17 passes through the eyelet and rests upon the member 11). ther-ehv forming a guide or support for the eyelet and holding it in position during the upsetting operation. The plunger ll will move downwardly with respect to the punch 17, the upper end oi' which will pass into the recess 32 formed in the handle. As the handle is moved in the opposite direction in' assuming its normal position. the pin i ill strike the rhoulder 26 of the recess -23. thus moving the member 19 back to its normal position in readiness for the next opr-ridion. and. as above de scribed. the return movement of the handle '2 will also through the arm 10 and the eyelet engaging member if teed the eyelets for ward so that another eyelet will be brought into operative relation with the plunger and the punch.

'hen the eyelets are formed in :1 connected strip, it is n(( ..-:-i;ll' that they should be separated from one another. and this accomplished by the mechanism clearly shown in Fig. 5, in which 27 indicates a cutting knife reciprocatingly mounted .in a recess 28 formed in the cutting block 13, and provided with a pin 29 engaging a recess 30 formed in the plunger ll. This recess 30 is so shaped that the initial downward movement of the plunger will causithe knife 27 to travel to the left, as show n in Fig. 5, with its sex ering edge. positioned below the point of connection of the cveleis in which position it remains stationary during the further downward movement oi the plunger. which morement of the plunger will force the connect- Y sition.

ing portion between the eyelets against the knife, thereby severing the eyelet which is being operated upon from the following eyelet. A further downward movement of the plunger 14 has no effect on the knife27, as the portion ofthe recess 30 which then engages the pin 29 is so arranged that further movement of the knife is prevented. As the plunger returns to its normal position, the knife 27 will be returned toits normal posi tion, as indicated in Fig. 5, and the various parts of the device are so adjusted that this return movement of the knife occurs prior to the forward feeding of the next eyelet.

The operation of the device is as follows: Assuming the parts to be in the position shown in full lines in Fig. 1, and assuming the eyelets to be as indicated in said figure, there will be one eyelet in operative relation to the punch 17 and plunger 14 and register ing therewith. As the handle 2 is pressed down, the punch 17 will pass through the eyelet and through the papers, after which the plunger, engaging the upper surface of the flange of the eyelet, will force the same past the spring 18 and through the hole formed in the, papers by the punch, it being understood that prior to the engagement of theplunger 14 with the eyelet, the knife 27 will have been moved to its operative position in readiness to permit the eyelet to be severed from the following eyelets. The plunger and punch will then be raised to free the latter from the hole or die 20 and the member 19 will be moved forward to bring the riveting recess 21 into registry with the lower edge of the eyelet. As the downward movement of the handle continues, the plunger 14 will be moved farther downward forcing the eyelet downward through the papers into the recess 21 and thereby upsetting or riveting the lower edge of the same; and, in the meantime, the arm 10 will have then moved backward to cause the member 12 to engage with one of the rearwardly positioned eyelets. As the handle returns to its normal position, the plunger and punch will be raised, after which the member 19 will be moved rearwardly to occupy its normal position, and the knife 27 will also 'be moved to occupy its normal po- As the handle reaches its original position the arm 10 will be actuated and the eyelets will then be fed forward so as. to bring another eyelet into operative relation to the punch and plunger in readiness for another operation of the machine.
